Test Method for Studying the Effect of Fuel Composition Upon Intake Valve Deposit Forming Characteristics

Source

This paper describes a test which was developed to measure induction system deposit-forming characteristics of gasolines. The procedure is a modification of the induction-system deposit test reported at the ASTM Symposium on Motor Gasoline Stability held in Philadelphia, Feb. 15, 1954. A baffled tube provides an extension to the test manifold where temperatures are of the order of those obtained on passenger car intake-valve stems.

Data are presented which compare the weights of baffled tube deposits with Chevrolet FL-2 engine and road tests intake valve deposits for three fuels. The effect of gasoline stability, antioxidant type, and concentration are discussed.
